The cdns-mhdp8546 bridge atomic_reset implementation is semantically
an atomic_create_state: it allocates and initializes a pristine state
without side effects.
However, it returns NULL on allocation failure instead of an error
pointer.
Switch to the atomic_create_state callback, rename the function
accordingly, and return ERR_PTR(-ENOMEM) on failure.
